Electronics And Communication Objective

GE 0106-Basic Engineering-II

The objective of this subject will help us to know the basic knowledge of Electronics. The concept of semiconductors, transistors, diodes, field-effect transistor, MOSFET their working principles, social structure and working model. To know about the a.c to dc converting circuits like half wave, exuberant wave rectifiers circuits. Also the filter operation of ripples utilise various types of filter circuits.
The various types of transducer working, aspect and uses will be discussed briefly and moving coil and moving iron instruments, thermistors, thermocouple, LVDT their construction and working principles are discussed.
The basic building of digital gate like AND, NAND, OR, NOR are studied. Also the conversion types of various reckon systems like hexa, decimal, octal, binary will be studied.
